Unable to Use dcmipp-isp-ctrl Tool at Runtime with IMX219 Sensor on STM32MP257-EV1

[dongremayur777]

I'm currently working with an IMX219 camera sensor connected to the STM32MP257-EV1 board. The camera is successfully streaming, and the pipeline appears correctly configured through media-ctl. However, I’m unable to use the dcmipp-isp-ctrl tool at runtime for ISP control.

System Info:

• Board: STM32MP257-EV1

• Sensor: IMX219

• ISP Tool: /usr/local/demo/bin/dcmipp-isp-ctrl

• Kernel & Yocto BSP: scarthgap

Media-ctl Output:

Camera is streaming properly; format and pipeline are configured as expected.

But the issue is 

Issue:

Running the following command:

/usr/local/demo/bin/dcmipp-isp-ctrl -i0 -g

I am getting output as 

00:00:47.8 / 99:99:99.
Can't find sensor subdev


Didn't understand what's going wrong , why it is unable to recognize the sensor.

Hello @dongremayur777 ,

The IMX129 is a RAW8/RAW10 bayer sensor.
To tune the dcmippp for this sensor and to get good color rendering, I suggest you to add the X-LINUX-ISP expansion package to your project:
https://wiki.st.com/stm32mpu/wiki/Category:X-LINUX-ISP_expansion_package

The dcmipp-isp-ctrl you are intended to use is no more the official way to use Raw bayer sensor. It is preferable to use Libcamera as depicted in the wiki page I have shared.

You should certainely need to update some of the IMX129 service to be supported by our ISP IQTune software to be able to properly tune the sensor image quality.
